How to calculate bandwidth of IP camera?
ipman replied to janekjan's topic in Installation Help and Accessories
The estimated bandwidth is 1 Mbit/s for H.264 High Quality compression. Storage space: 330 GB for 30 days if using constant recording. But who uses a constant recording now? Usually the usage of a motion detector limits the storage space maybe 5 times or so depending on motion activity. Unfortunately our new bandwidth calculator doesn't support such old camera resolutions as 720x576 because we removed unpopular camera resolutions. But you still can calculate such resolutions using a trial version of ip video system design tool where you can add your camera 720x576 resolution. In fact you can add any custom resolution to the program. -
New CCTV lens calculator with 3D graphics, DORI and DB
ipman posted a topic in Installation Help and Accessories
We have created the new free online lens calculator that shows field of view in 3D and displays DORI zones. https://www.jvsg.com/calculators/cctv-lens-calculator/ For additional convenience you can choose camera models from a database of camera models. The database of camera models is the same as in IP Video System Design Tool. You can switch the lens calculator to Imperial (Feet) or Metric (meters) mode. Fisheye and multi-sensor cameras are not supported in the calculator. Pixel density values for DORI zones are based on EN62676 standard. Additionally the user can load a site map.- 1 reply

It does worth to import your site plan into any Cctv design software to check pixel density at 100-150 m distance. If by detect face/license plate you mean recognize you will need at least 125 pixels per meter. If you need a picture quality for identification you will need 250 pixels per meter. I think you will be surprised.

Do you have a site plan? Or maybe you can draw a site plan using a demo version of IP Video System Design Tool, then add a camera to see coverage area and identification/recogntion/observation zones This way you can test different scenarios and find the optimal position for your camera.

We plan to create training materials that will go with our JVSG design software. I am looking for a native English speaker who is familiar with video surveillance design. Actually, we are looking for people for 2 different tasks: 1. Rewrite CCTV training materials on video surveillance design from bad English to good English (you should understand well what is lens focal length, pixel density, e.t.c) 2. Write new articles, advice, tips, and tricks related to CCTV design process (you should have a solid experience in designing/installing video surveillance systems). please contact me by email at max @jvsg.com

Hi, can you please give more details? I don't understand what you would like to get. -
Newbie Help - Camera Type and Location Advice
ipman replied to MikhailCompo's topic in System Design
To find optimal camera locations and to simulate 3D view that takes your camera installation height in consideration you can use a trial version of IP Video System Design Tool. It will also show you zones of identification (250PPM), recognition (125PPM), e.t.c -
You are quick! The time difference between your last 2 posts is 1 hour and 5 minutes.

Sure. It was just an illustration. The design process is not automatic. And you are right that the CCTV designer should take care of entrances and windows. This was just an illustration of how the software visualizes identification, recognition, detection and monitoring zones and can show you 3D views from your CCTV system. Some of our users asked us if we could implement an automatic camera placement algorithm. But experienced human CCTV designers are way better than a machine in analyzing security threats.

You can take a trial version of IP Video System Design Tool, like I have shown in that topic. load your site plan and add your cameras, add obstacles (trees, cars) and test people and finally see what images you will get on your DVR/ NRV. The most important thing that you will be able to see identification/recognition zones based on pixels per meter or pixels per foot. 250 PPM or 76 PPF for Identification of people (by European standard EN62676-4) 125 PPF or about 38 PPF for Recognition of people. e.t.c. IMHO your camera positions should be revised. For example, I don't understand the idea behind Camera 10 position. You can easily rotate Cam10 left (about 30 degrees) for a better view. Unfortunately, I cannot see the real size of your house to accurately re-scale your drawing.

Do you have a floor plan (JPEG, PNG, PDF or DWG)? Please attach it here or do try to load it yourself into our cctv design software like I shown in this topic
